When I lived in Staten Island, I had two outdoor compost bins and I loved it. I had this fancy one, and this DIY one that I made. However this year, I moved to Manhattan, and not only did I have to give up my amazing backyard and garden, I also had to give up my compost bins. I didn't however, give up on composting. I found out that on Saturdays at the farmer's market 2 blocks away, they collect compostable organic material. I go through a lot of fruit, veggies, coffee, and eggs, so I had to start putting the compost in the freezer since it was starting to attract fruit flies.
vermicomposting / worm composting. "Charlotte Douglas International Airport has deployed an army of 1.9 million worms to eat through its organic waste. The airport has reduced the trash it sends to the landfill by 70 percent." They sort the airport's trash and separate the recyclables out of the garbage and all of the compostable organic material goes into a big tank with earthworms! The earthworms "eat half their body weight in organic material a day". The worm poop gets used within the gardens around the airport or sold. If only New York City could adapt these worm composting methods! I bet we could save a lot of waste and make money in the process!
